Kevin Ansfield b24e121eb3 Fix shortcut keys sometimes not being cleared due to scope changes
closes #5813
- when transitioning away from a shortcuts route, always specify the scope when unbinding in keymaster to avoid issues when we are temporarily be in a different scope at time of transition

/**
* Only routes can implement shortcuts.
* If you need to trigger actions on the controller,
* simply call them with `this.get('controller').send('action')`.
*
* To implement shortcuts, add this mixin to your `extend()`,
* and implement a `shortcuts` hash.
* In this hash, keys are shortcut combinations and values are route action names.
* (see [keymaster docs](https://github.com/madrobby/keymaster/blob/master/README.markdown)),
*
* ```javascript
* shortcuts: {
* 'ctrl+s, command+s': 'save',
* 'ctrl+alt+z': 'toggleZenMode'
* }
* ```
* For more complex actions, shortcuts can instead have their value
* be an object like {action, options}
* ```javascript
* shortcuts: {
* 'ctrl+k': {action: 'markdownShortcut', options: 'createLink'}
* }
* ```
* You can set the scope of your shortcut by passing a scope property.
* ```javascript
* shortcuts : {
* 'enter': {action : 'confirmModal', scope: 'modal'}
* }
* ```
* If you don't specify a scope, we use a default scope called "default".
* To have all your shortcut work in all scopes, give it the scope "all".
* Find out more at the keymaster docs
